Definitions

  • the proposed invention relates to method of producing protective security holograms.
  • the drawback of the above method is in its insufficient manufacturability, which is due to necessity to provide electroconductive layer on the matrix surface.
  • Chemical nickel-plating is used to create such electroconductive layer on the matrix surface.
  • this operation is not sufficiently controllable, therefore, the layer turns to have different thickness over the matrix area, and, on the other hand, it is very sophisticated technologically and quite expensive, which makes the use of this method limited.
  • a method of producing a protective security hologram which includes the following operations: producing the desired image, recording a hologram of the desired image, producing metal matrix of the desired image hologram, further replication of a protective security hologram on polymer film by way of matrix embossing ( Joseph R. Burns., "Large format embossing holograms", Proceedings of SPIE, vol. 523 ).
  • the method described above provides for optical recording of images (optical recombination) with further creation of the electroconductive layer on the surface of recorded hologram, which is necessitated by the need to use the operating surface of hologram replicating machine in full and to ensure required number of repetitions.
  • electroconductive layer is created after recording the hologram or after optical recombination.
  • Such necessity significantly decreases the manufacturability of the method. For example, in case if a desired image comprises large number of individual small images, sophisticated operation of optical recording of holograms should be repeated the number of times equal to the number of individual holograms contained in the desired image. An error in any operation of described method causes the need to repeat the whole technological cycle. Creating electroconductive layer is required to enable production of the matrix using an electroforming process.
  • the proposed invention shall provide more manufacturable method of producing protective security holograms. This problem is resolved by way of creating conditions for mechanical forming of replicas of a protective security hologram on the surface of electroconductive polymer or polymer layer with electroconductive coating.
  • the method according to the proposed invention includes the following operations: producing a desired image, recording a hologram of the desired image, producing a metal master of the desire image hologram using an electroforming process, coating a polymer material surface with electroconductive layer, then, using mechanical recombination method, i.e.
  • metal master embossing producing on the surface of existing electroconductive layer, a polymer master matrix, such that it includes a number of holographic images and reproduces an image being mirror replicas of the desired image hologram producing on the polymer material surface a metal master matrix by means of an electro forming process and protective security hologram is replicated on a polymer film by embossing said metal master matrix.
  • the solution of the problem has become possible in the proposed method due to preliminary coating of the surface of the polymer material with electroconductive layer intended for using an electroforming process.
  • the metal master produced replica is a metal mirror of the desired image (relief) and may be used a needed number of times to mechanically reproduce the hologram of the original relief on the surface of electroconductive polymer or polymer layer with electroconductive coating.
  • An electroconductive polymer or polymer with electroconductive coating layer sensitive to mechanical deformation may be used in the proposed method.
  • Said layer is formed in a separate operation and it may be used to produce the metal master matrix, provided that its electroconductivity is sufficient to enable metal depositing by way of electroforming.
  • Mechanical reproduction is performed on a conventional equipment - a mechanical press for recombination.
  • an embossing shim having longer life that the metal master matrix, may be produced using the metal master matrix by way of electroforming copying of its surface.
  • Polymer film is coated with electroconductive layer using chemical nickel-plating method, for example, by way of immersion of the film with activated surface into nickel chloride and sodium hypophosphite solution of necessary concentration until nickel coating layer of needed thickness (i.e. 0.10 to 0.15 ⁇ m) is formed on the film surface (see, f.i., N.V. Odnoralov, Electroplating in decorative arts. - M.: Iskusstvo. - 1952.- 208 p .).
  • Hologram 2 is created of each individual image 1 by way of its recording on photosensitive layer (not shown on the figure). Hologram 2 is formed by two laser beams 3 and 4, one of which passes through photomask 5 with desired individual image 1. Using electroforming process the image being a mirror of said individual image is formed of a metal layer starting from the photosensitive layer. Thus, individual metal master 6 is produced. Then, using mechanical recombination, a holographic image is reproduced by means of the metal master 6 of individual holographic images 2. Thus, the polymer master matrix 7 with electroconductive layer is formed. Metal master matrix 8 is created by electroforming process and is used for replication of protective security holograms.
  • electroconductive layer is formed within separate operation of depositing and may be used directly for producing the polymer matrix 7 provided that its electric conductivity is enough for using the electroforming method
  • the proposed method is more manufacturable and, at the same time, enables increase in quality, because sophisticated process of repeated optical recording of holograms on photosensitive layer is replaced by simple operation of mechanical reproduction of holographic relief on electroconductive polymer layer.
